                 Notes to the Consolidated Financial Statements

         This report  should be read in  conjunction  with the Annual  Report on
Form 10-K for the year ended December 31, 1996, and the Quarterly Report on Form
10-Q for the  quarters  ended  March  31,  1997 and June 30,  1997 of  Alleghany
Corporation (the "Company").

         The  information  included in this report is unaudited but reflects all
adjustments  which,  in the  opinion  of  management,  are  necessary  to a fair
statement of the results of the interim periods covered thereby. All adjustments
are of a normal and recurring nature except as described herein.

Contingencies

         The Company's  subsidiaries  and division are parties to pending claims
and litigation in the ordinary course of their  businesses.  Each such operating
unit  makes  provisions  on its  books in  accordance  with  generally  accepted
accounting  principles  for estimated  losses to be incurred as a result of such
claims  and  litigation,  including  related  legal  costs.  In the  opinion  of
management, such provisions are adequate as of September 30, 1997.

ITEM 2. MANAGEMENT'S  DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATION.

         The Company reported net earnings of $30.0 million in the third quarter
of 1997,  compared with $19.9  million in the third  quarter of 1996,  and $76.9
million in the first nine  months of 1997,  compared  with $59.5  million in the
first nine months of 1996.

         Net losses on  investment  transactions  after  taxes in the first nine
months of 1997 totalled $601  thousand,  compared with net gains of $1.4 million
in the first nine months of 1996.

         Chicago Title and Trust Company ("CT&T")  contributed  pre-tax earnings
of $30.2  million on  revenues  of $391.3  million  in the 1997  third  quarter,
compared with $17.8  million on revenues of $358.3  million in the third quarter
of 1996. In the first nine months of 1997, CT&T contributed  pre-tax earnings of
$72.6  million on revenues of $1,088.3  million,  compared with $57.0 million on
revenues of $1,013.2 million in the first nine months of 1996.

         CT&T's  results  in the third  quarter  and first  nine  months of 1997
reflect strong activity in commercial  real estate markets and increased  escrow
and title search  information sales revenue.  1996 nine-month results included a
$4.2 million pre-tax charge to write down the carrying value of title plants and
goodwill in connection with the implementation of Financial Accounting Standards
Board  Statement  No. 121,  and pre-tax  income of $8.0  million in respect of a
reduction in title claims reserves.

         CT&T's  results  also  reflect an increase in the  contribution  of its
financial services businesses conducted through Alleghany Asset Management, Inc.
and its subsidiaries ("Alleghany Asset Management").  Alleghany Asset Management
contributed  pre-tax earnings to CT&T of $6.6 million in the 1997 third quarter,
an  increase  of 94 percent  over the 1996 third  quarter  contribution  of $3.4
million,  and $17.2  million in the first nine months of 1997, an increase of 81
percent over the  contribution of $9.5 million in the first nine months of 1996.
The improved  results of Alleghany  Asset  Management  are  primarily  due to an
increase in assets under management.  As of September 30, 1997,  Alleghany Asset
Management  managed $21.3  billion in assets,  compared with $13.4 billion as of
September 30, 1996.

         Underwriters  Re Group,  Inc.  ("Underwriters  Re  Group")  contributed
pre-tax  earnings of $9.8  million on  revenues  of $115.1  million in the third
quarter of 1997, compared with $8.9 million on revenues of $109.8 million in the
third quarter of 1996,  and $31.7  million on revenues of $337.6  million in the
first nine  months of 1997,  compared  with $23.9  million on revenues of $315.6
million in the first nine months of 1996.

         The results of  Underwriters  Re Group for the third  quarter and first
nine months of 1997  reflect  flat  reinsurance  premium  levels due to a highly
competitive and soft reinsurance  market, an absence of significant  catastrophe
losses and an absence of adverse reserve activity.  Net written premiums for the
third  quarter of 1997 were $99.0  million  compared  with $92.3  million in the
prior year third  quarter,  and $310.4 million for the first nine months of 1997
compared  with $298.2  million in the prior year first nine  months.  1996 third
quarter  results also reflected a pre-tax gain of $1.0 million on the sale of an
equity investment.

         World Minerals Inc. ("World Minerals")  contributed pre-tax earnings of
$8.3 million on revenues of $53.0  million in the 1997 third  quarter,  compared
with $4.2 million on revenues of $52.1  million in the third quarter of 1996. In
the first nine months of 1997,  World Minerals  contributed  pre-tax earnings of
$18.2  million on revenues of $152.8  million,  compared  with $14.3  million on
revenues of $151.0 million in the first nine months of 1996.

         World  Minerals'  revenues and pre-tax  earnings  increased in the 1997
third  quarter from the prior year period due to a more  profitable  product mix
sold by the World Minerals' North American  diatomite plants,  and higher export
volume in its Latin American diatomite plants without a commensurate increase in
operating  costs.  1997  nine-month  results  reflect the improved  results from
diatomite  operations  offset by continuing high start-up costs related to World
Minerals' Chinese joint ventures and the continued  strength of the dollar which
lowered the results of foreign  operations.  1996 third  quarter and  nine-month
results  included a charge related to the purchase of minority  interests in one
of World Minerals' businesses.

         As of September 30, 1997, the Company  beneficially owned approximately
7.43  million  shares,  or 4.8  percent,  of the  outstanding  common  stock  of
Burlington  Northern Santa Fe Corporation which had an aggregate market value on
that date of approximately $718.1 million, or $96.625 per share, compared with a
market value on December 31, 1996 of $641.9 million,  or $86.375 per share.  The
aggregate cost of such shares is  approximately  $253.7  million,  or $34.15 per
share.

         The  Company's  results  in the  first  nine  months  of  1997  are not
indicative  of  operating  results  in  future  periods.  The  Company  and  its
subsidiaries  have  adequate  internally   generated  funds  and  unused  credit
facilities  to  provide  for the  currently  foreseeable  needs of its and their
businesses.


                           PART II. OTHER INFORMATION

ITEM 2.  CHANGES IN SECURITIES.

         (c)   Recent Sales of Unregistered Securities.

         On October 3, 1997,  Alleghany  issued an aggregate of 82,573 shares of
Alleghany  common stock to ten employees of Underwriters Re Group pursuant to an
offer by Alleghany to exchange 431,696 shares of common stock of Underwriters Re
Group (the "URG Shares") held by such employees,  which  represented 2.7 percent
of the  outstanding  common  stock of  Underwriters  Re  Group,  for  shares  of
Alleghany  common  stock at an exchange  rate of  .191264368  share of Alleghany
common  stock for each URG  Share  (rounded  up to the  nearest  whole  share of
Alleghany  common stock).  Alleghany now owns all of the issued and  outstanding
URG Shares.  The exchange was exempt from registration  under the Securities Act
of 1933, as amended (the "Securities Act"), pursuant to Section 4(2) thereof, as
a transaction not involving a public offering.


         On October 3, 1997,  Underwriters  Re Group granted options to purchase
an aggregate of 202,102 shares of Alleghany common stock for an average exercise
price of $132.44 per share (the "New  Options") to sixteen  employees and former
employees of Underwriters Re Group pursuant to an offer by Underwriters Re Group
to exchange  options to acquire an aggregate of 1,056,522 shares of common stock
of  Underwriters  Re Group  held by such  persons  (the "Old  Options")  for New
Options,  at the exchange rate set forth above.  One-quarter  of each New Option
becomes exercisable on each of the first, second, third and fourth anniversaries
of the date of grant  of the Old  Option  which it  replaced.  A New  Option  is
forfeited  to the extent not  exercisable  upon  termination  of the  optionee's
employment  with  Underwriters  Re Group or a  subsidiary.  The grant of the New
Options  was exempt  from  registration  under the  Securities  Act  pursuant to
Section 4(2) thereof,  as a transaction  not  involving a public  offering.  The
shares of Alleghany  common stock  issuable upon the exercise of the New Options
have  been  registered  on  Alleghany's   Registration  Statement  on  Form  S-8
(Registration No. 333-37237).

         The above does not  include  unregistered  issuances  of the  Company's
common stock that did not involve a sale consisting of issuances of common stock
and other securities pursuant to employee incentive plans.

ITEM 5.  OTHER INFORMATION.

         On August 14, 1990, the Company transferred a $91.5 million installment
note issued by Merrill Lynch, Pierce, Fenner & Smith Incorporated,  the maturity
of which was extended from 1994 to 1999 (the  "Installment  Note"), to Alleghany
Funding  Corporation,  a wholly  owned  subsidiary  of the Company  ("AFC"),  in
exchange for the common stock of AFC. On that date, AFC issued secured notes due
1999 in the aggregate principal amount of $80 million ("1999 Notes").

         On October 20, 1997, AFC redeemed the 1999 Notes with the proceeds from
the issuance by AFC on that date of secured notes due 2007 (the "2007 Notes") in
the  aggregate  principal  amount of $80 million.  The 2007 Notes are  primarily
secured by (i) the Installment Note, the maturity of which was extended to 2007,
pursuant to an intercreditor and collateral agency agreement (the "Intercreditor
Agreement")  among  AFC,  The Chase  Manhattan  Bank as  collateral  agent,  and
Barclays Bank PLC as swap counterparty,  and (ii) a master agreement and related
amended confirmation (collectively,  the "Swap Agreement") between Barclays Bank
PLC as swap  counterparty  and AFC,  pursuant to an indenture (the  "Indenture")
between AFC and The Chase Manhattan Bank as trustee. The Swap Agreement provides
that AFC shall pay to Barclays  Bank PLC a portion of the  interest  received on
the Installment Note, which is based on a commercial paper rate, and, in return,
Barclays  Bank PLC shall pay to AFC an amount  equal to the interest on the 2007
Notes, which is based on a LIBOR rate. The 2007 Notes were privately placed with
several institutions.

         The  foregoing  summary  description  is  qualified  in its entirety by
reference to the Intercreditor  Agreement, the Swap Agreement and the Indenture,
attached hereto as Exhibits 10.1 through 10.3, respectively.
